ABSTRACT
Obtaining virus free fruit planting material, conservation and utilization for large scale production of certified fruit trees, was and is still an objective demand. It knows already that significant cultural performances achieved by fruit trees, are direct related to the biological value of planting material used. Often it is necessary to introduce rapidly in culture new varieties and, this it is possible through tissue culture. Tissue culture is commonly called "cloning" or "micropropagation". In horticulture, the micropropagation is the most recent method used for the commercial plant propagation as a biotechnology application. At Research Institute for Fruit Growing Pitesti ArgeĊŸ strawberry was one of the first plant species introduced in the in vitro culture. In the `90, extensive research in many other fruit species, have to develop rapid and efficient procedures for mass clonal propagation. Also, sustained efforts are towards the development and verifying of biotechnology procedures for efficient propagation of the new created fruit varieties. Propagation systems approved by actual legislation regarding production of fruit tree planting material include also micropropagation as propagation technique. Data presented in this paper describe validated protocols for micropropagation of some varieties of strawberry and raspberry. These protocols tested had favorable results for more than five years and can thus be considered validated. This paper presents the data regarding aseptic cultures establishment, culture media, hormone combinations, culture conditions and specific technical parameters for fruit species and the role and importance of tissue culture in certification schemes.
